I'm looking for something the will go under the unit plinths to seal it against the wooden floor, preventing dust and the like from getting under the units. I found some stuff:- [URL]http://www.kitchen-storage.co.uk/product2_912-1-71-1820_Plinth-Sealing-Strips,-18-19-mm-Panels.htm[/URL] but I'm not keen on the prospect of a plastic strip running the whole length of the units, spoiling the wood on wood action (fnarr). The floor's not 100% level so there are varying gaps against the plinth of 1-3mm. What about some of those soft foam seals that are sometimes put around doors to keep drafts out? They look quite thick, although I suppose they're very squishy in order to fit on the inside of a door jam.
